摘要

摘要: 报道了首次在大兴安岭中南段侏罗系火山-沉积地层中发现的木化石。化石产于内蒙古自治区科尔沁右翼中旗地区满克头鄂博组中酸性火山碎屑沉积岩中，经沈阳地质矿产研究所张武研究员详细鉴定，有5属3个已知种和2个未定种。对新发现木化石的主要特征进行了描述，讨论了木化石的时代。综合分析所发现化石的组合特征，认为其时代属中晚侏罗世。这些木化石新材料为大兴安岭地区上侏罗统地层区域对比提供了新的古生物资料依据。

Abstract: This paper reports the fossil woods found for the first time in the Jurassic volcanic-sedimentary strata in the central-southern part of the Da Hinggan Mountains. The fossils occur in the intermediate-acidic pyroclastic sedimentary rocks of the Manketouebo Formation in Horqin Right Wing Middle Banner of Inner Mongolia. According to detailed identification, there are 5 genera with 3 known and 2 unknown species. The main features of these fossils are described and their ages are discussed. A comprehensive analysis of the combinational features indicates that the fossil woods are middle stage of Late Jurassic in age. The newly found fossil woods provide new paleontological evidence for regional stratigraphic correlation of Upper Jurassic strata in the Da Hinggan Mountains region.
